# Yamaha CS-01
“This is a fully working Yamaha CS-01 Mk 1 monophonic synthesiser, great for basslines and fully portable.
All sliders, switches and keys are present and correct. This synth is in excellent working condition (note- I have never owned a BC-1 breath controller so have not tested this feature)
The synth is missing the battery cover, however, I have used this synth with batteries and can assure you that they remain firmly in the compartment. The casing is scratched, the majority of it on the underside.
Also included:
* correctly rated 12V power supply (non Yamaha) that I have used to operate this synth
* downloaded instruction manual
* downloaded service manual” Link
